7'0 all whom it may concern:

Be it known that I, Jones L. Srannss, a citizen of the United States, and a resident of the city of New York, borou h of Manhattan, in the county and State oi New York, have invented a new and Improved Portable Electric Lamp, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a movable electric lamp having a flexible connecting wire, with means for automatically and at will gathering a portion of said wire; to provide a gathering mechanism for electric lamp cord, said mechanism being adapted'to wrap said cord in a coil of small compass; to provide a portable lamp having a hinged standard rotatable to vary the plane of the swing of said standard; to provide a rotatable lamp-supporting standard and a non-rotatable supporting ase therefor; and to provide electric-circuit connections disposed in said base-to permit lndependent movement of the lamp-supporting standard above referred to.

Drawinga.-Figure 1 is a side view of a lamp constructed and arranged in accordance with the present invention, the broken lines shown therein being used to illustrate some of the various positions to which said lamp may be moved in service; Fi 2 is a vertical section through the base s own in Fig. 1, the lamp standard being in part broken away; Fig. 3 is a cross section taken on the line 83 in Fig. 2; Fig. 4 is a detail view in vertical cross section of a cord-winding reel taken as on the line 4-'l in Fig. 5; Fig. 5 is a horizontal section taken as on the line 5-5 in Fig. 2; Fig. (5 is a horizontal section taken as on the ine 6-45 in F ig. 2; Fig. 7 is a horizontal section taken as on the line 'l'-7 in Fig. 2; Fig. 8 is a view'of the bottom of the lamp base, the view being taken as from the position indicated by the 1 of the drawings. Fig. 9 is a side view ot a lamp base having spring slide plates and arms for supporting the base on a standing structure.

Descriptio'n.-As seen in the drawings, the

electric-light globe is mounted in a socket 16. The socket 16 is provided with a switch embodying an operating button IT. The socket 16 is mounted on the end of a short standard 18, the lower end whereof is pivotally mounted by means of a pin 19 between the sides of a yoke 20. In Fig. 1 of the drawings several positions are illustrated to which the lamp may be moved. When the lamp has been properly positioned with reference to the base and the short standard 21 thereof, a clamping nut 22 is manipulated to bind the knuckle on the standard 18 in the yoke 20. Mounted upon the globe 15 is a shade 24. The shade 24 is held in service relation to the globe 15 by hollow-centered gripping loops 25. The formation of the 00 s 25 and the grip of'thc same on the glo e 15 are such that the shade may be moved around said globe, or pivoted to swing In certain service positions of the base 2e said base remains in the osition in which it is set. As seen best in Fig. 8 of the drawings, I rovide arms 27, disposed each at one end of t e slide plates 28. are-slidably mounted in a roove formed in the base 26, and are botli provided with elongated slots which infold a screwthreaded pin 29. The pin 25), in conjunction with a slot formed in the base 26, constitutes a satisfactory guide controlling the movement of the )lates 28. As shown by the dotted lines in 1 1g. 8, the plates 28 are extended to permit the arms .27 to be passed behind a shelf or rail (31, as seen best in Fig. 9 of the drawings. Said rail. it will be understood, forms part of a standing structure. When the plates 28 are satisfactorily adjusted, at screw-nut 31 is set up on the pin 29 to force the plate 32' upon the lapped portions of said plates 28, to hold the same definitely in the adjusted position.

To hang the lamp on the side wall of a standing structure there is provided a sliding eyelet plate 32. The plate 32 is mounted in a groove 33 and is )rovided adjacent the outer end with an eyelet 34. The plate 32 is held in the groove 33 by a screw 35.

about the same as on a pivot member.

The slide plates which screw passes through an elongated slot 36 in said plate 32,

The standard .21 is constructed of tubing, and at the lower end is pivotally seated in a recess provided in the base 26. The standard 521 is held firmly in position by a machine screw 37. The up )tl end of the stand-- ard 21 is furnished wit i a stop meinberBS, which rests firmly upon the to) of a thin metal canopy 39. The interior oi the canopy 39- forms a hollow chamber, wherein op erates a winding reel for the lamp-cord 4O and for a contact plate 41. The contact late 41 is constructed from suitable insu- 'ciiit main 46, as shown best in Fi f2 of'the drawings. The main 40 is passe through an opening in the side of the standard 21, and is extended upward therethroug'h tobe wrap ed onthe pin 19, from whence it,is led tirough the standard 18 to the te'rmi-' nals of'the switch contained intlie soc'ke'tlfi.

From tlieforegoing it is obvious tliatlthe lamp embodying the standards 18 and 21 may be revolved without disturbing the main 46, and, as hereinafter-set.forth, may remain stationary while the windingre'el is oper'atedjto gather the lamp-cord 40.

The reel for gathering the lam -cord 40 embodies an insulating tabled'i'. Ihe 'table 47 is; se aratcd from the -ratchet-toothed late 48 y means of a hub 49. The hub 49 is tubular in form and has a reducedend 50, the lower edge thereof rests on the upper snrfaceof 'the base.26 to su port the reel in service. The table '47 and flate '48'aie structurally united by screw olts '51, as bestseen 'in Fi '4 o the drawings. The reel so formed is operated by a coil spring 52, which sprin rests beneath the plate 18 upon the base 2 Current'is coni'eye'dfroni the two strands of the cord 40 to the rings 44 and 45 on the plate41 by nie'ansof spring wiper contacts 53 and 54. The contacts 53 and M are held in position on the table 47 by bolts 55. The under surface ofthe table 47 is suitably recessed to receive in c'oiintersunk relation the bolts 55 and the split strands of the cord 40.

From the foregoin is'obviousthat when in service, the amp may be placed 'in any suitable position, an'dithe cord '40 may be extended to accommodatetlie'morement of said lam It is alsoevid'eiit that 'the spring 62 wii normally maintain the the spring pull on the cord 40, to wind the same on the hub 49, It will also be noted that. irrespective of the position of the base 26 and canop 39, the standard .21 and parts councctec therewith. including the lamp 15, rotate freelv without disturbing said base or the cord alt connected therewith and leading therefrom It is to hold the reel in position to provide sufiicicnt slack in the cord 4-0, that I provide the plate 48 with ratchet teeth, such as 56, and a spring-actuated pawl 67 to ciiglage the same. The pawl 57, as seen best in 1g. 7 of the drawings, is pivoted to the pin I38 and has a tail extension 59 provided with a button that protrudes from the side of the canopy 39. he pawl 57 is actuated by a flat spring 60 to norinallv en age the teeth 56 as the same pass under the latch head. \Vhen it is desired to release the plate 48 and reel connected therewith to permit 52 to take in any slack which exists in the cord 40, the operator by pressin'g upon the button connected with the extension 59, disengages the latch 57 from said plate,
